The Mark of Cain (1947) Reviews

In this costume drama, a woman finds herself the prize in a battle between two jealous brothers. Eventually she marries the suave one, but finds that he is most displeased by her inability to behave in a matter he deems appropriate for a woman of her station. The sad wife takes her troubles to the other brother who suggests she divorce her husband and take up with him. She ignores the advice and reconciles with her man. The angered brother then poisons the husband and tries to get the wife blamed for the death. ~ Sandra Brennan, Rovi
